Computer Fundamentals and System Concepts

Servers are fast computers that run various software's, store and process information and also provide a human interface to the user to use the networked computers.

Writing the microcode is often called microprogramming and the microcode in a particular processor implementation is sometimes called a microprogram. Microprogramming is the designing of the CPU.

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs.

In computing, an arithmetic and logic unit (ALU) is a digital circuit that performs integer arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers.

The 8086 is a 16-bit microprocessor chip designed by Intel between early 1976 and mid-1978, when it was released.

The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is a processor register that indicates where a computer is in its program sequence.

CPU modes are operating modes for the central processing unit of some computer architectures that place restrictions on the type and scope of operations that can be performed by certain processes being run by the CPU. This design allows the operating system to run with more privileges than application software.

It is a branch of computer science whose goal is to design and develop machines that emulate human brain power.

Yes, central processing unit will perform the transformation of the input to output.

Yes, operating system manages the memory, prevents others to access the files and access the I/O devices.

Yes, 0 is the lowest binary number.

Yes,  the fault in computer program prevents it from working correctly is called as bug.

Yes, it is correct. It is an example of application software .It consistes of dreamwaver, flash, freehand.

Yes it's correct choice. 8 - bit means it has 8 - data lines

This group provides the 8085 with mathematical ability to manipulate 8-bit data and by judicious use of the condition codes manipulate larger values. Data transfer group of instructions provide 8085 with the ability to move data around inside the RAM, between the RAM and the register of the microprocessor and between registers within the microprocessor.
